Modify
the Deans video as follows:
1. You do need to attach the plug's mate,
to maintain proper terminal
alignment.
This also makes it
easier to clamp the
plug to the bench.
2. Do a more complete job of tinning the
plug terminals.
3. Clamp the plug so the terminals are
horizontal when you tin
each one, and
also when each wire is
soldered. This
allows the solder to flow better
4. After the first wire is soldered, slide the
shrink tubing over the
joint, to prevent
the iron tip from shorting the battery
when the second wire is
soldered.
